ABSTRACT

INVENTION FIELD

The present application claims the priority benefit of Brazilian PatentApplication No. BR 1020120310589 of 6 Dec. 2012.

The present invention describes a clothing for the practice of aquaticsports equipped with lumens for filling in of air and the respectivewelding method of the lumens' periphery through sinuous or brokenwelding lines which assure the maintenance of the elasticity andamplitude of movements, avoiding the rigid areas that appear when thetechnique of straight line collage is used.

INVENTION PRECEDENTS

The clothing for aquatic sports is generally made of neoprene, anelastomeric material provided with elasticity and high resistance whichallows thermal comfort to the user. However, this clothing does notpresent means to assure the user's survival in case of water immersionfor a long time, or, yet, does not present means for assuring itsfloating.

Thus, deaths of surfers and other aquatic sports practitioners throughdrowning are not avoided. For example, in case of a consciousness lossin water or immersion for a long time, the clothing does not present anymeans to maintain the user floating, in a manner to assure oxygenationand life.

Patent number BR0104789, from the same holder, describes a life-savingclothing made of waterproof material having a series of lumens orcompartments positioned next to the neck, throughout its front and backportions, whereby such compartments retain a special gas derived from achemical reaction which maintain the lumens inflated in order to keepthe user's head and nose outside of the water, avoiding death throughdrowning in case of eventual unconsciousness.

The state of the technique describes other solutions, such as thedocument BRPI9600469, which presents an anti-drowning safety deviceattachable to pieces of clothing that involves an inflatable vest madeof waterproof thermoplastic material, which is rolled down in the formof a thick belt and attached to the waist of a piece of clothing bymeans of a Velcro® fastener or the like, said of a device having a smallreservoir containing air under pressure, having a needle valve commandedby a pin next to its shaft.

The document BR0102839 describes an inflatable multiple multi-userlife-saver which involves an inflatable recipient with a cavity thatcrosses it from one side to the other, forming a type of tunnel orchamber, whose interior contains a fastening device destined to fix andmaintain the individual totally safe and protected, during rescue, anddevices capable of inflating and/or emptying and shooting gases withgreat expansion power in the container's inside.

Considering the clothing used for the practice of aquatic sports,generally with elastic surface, the conformation of lumens for thefilling in of air is obtained through the collage of two superimposedtissue blades with waterproof properties, where neoprene isconventionally used. However, the collage in straight line or in extensestraight segments generates an area deprived of elasticity, which makesthe amplitude of the user's movements difficult, mainly in the shoulderregion. Still, the collage can generate air overflow in between thetissue fibers, in case it's not accurately made.

Thereby, clothing for the practice of aquatic sports is the object ofthe present invention, which presents the conformation of lumens withperiphery provided of sinuous or angled welding lines that generate aspring effect, providing elasticity which does not limit the user'smovement amplitude, situation required in aquatic sports.

Additionally, it's the object of the present invention a welding methodfor obtaining such lumens applied in clothing for the practice ofaquatic sports where alternative forms of tissue welding are predictedin a manner to provide a barrier to air dissipation between the clothingfibers.

DETAILED DESCRIPTION OF THE INVENTION

The clothing for the practice of aquatic sports having lumens for thefilling in of air involves a Neoprene® clothing (100), an elastomer madeup of dubbed polycloropen rubber with nylon tissue on both faces andwith impermeability properties, isothermal and elastic.

The clothing (100) presents in specific areas the disposition of lumens(10) obtained by the welding of two neoprene and/or similar bladessuperimposed (110), such lumens (10) limited on the periphery by sinuousor angled welding lines (20), in a manner to avoid the formation of aninelastic area when the welding occurs in straight lines.

The lumens (10) can be positioned in the chest's region and/or in theproximity of the neck and/or on the dorsal or lumbar regions.

The sinuous and/or angled welding lines (20) eliminate the conformationof long straight lines that form inelastic areas which make theamplitude of movements more difficult. On the contrary, the sinuous andangled welding lines (20) provide a spring effect, particularly usefulin the shoulder's area, where an intense motion of the region for therowing is required, such as flexion, extension, abduction,hyperextension, adduction and internal rotation.

Optionally, the lumen (10) presents on the inside the arrangement of aninner tube made up of of elastic material (101), as presented in FIG. 4,whose tube (101) can present on the internal surface the application ofa layer of paint or similar (21), preferably through silk screen orspatuling process, whose layer of paint or similar (21) which provides aphysical barrier to the overflow of air contained in the lumen (10)through the tissue's fibers, as presented in FIG. 6.

Optionally, the lumen (10) presents on its inside the disposition of atube (102) with its surface provided with intercalated reliefs andundulation, called flat springs (1021), as described in documentPI8702823, from the same holder, allowing elasticity to inelasticsurfaces, as presented in FIGS. 5 and 5A.

For the filling in of air from the lumen (10) or from the inner tube(101) a bidirectional biting valve (11) is predicted, preferablypositioned at the front of the clothing (100), whose valve (11) iswithin easy access to the user's mouth when wearing such clothing (100),allowing the entrance of air into the lumen(10) or into the tube (101)and return to the lungs, in case of a complementary oxygenation need,through the disposition of the mouth on the valve (11).

Preferably, on the inside of the lumen (10) profiles (12) which moveaccording to the air flow established from the valve (11) aspiration arelaid out, such profiles (12) which configure internal protuberanceswhich facilitate the passage of air in its totality, be it on thefilling in or emptying of the lumen (10), mainly in strangulation areas,where the material's elasticity can imply in the restriction of exit orentrance of air, as presented in FIGS. 1 and 2.

The lumens (10), by being filled in with air, keep the chest elevated,lessening the effort during the rowing, as is the case when surfing.Still, the lumens (10) assure the user's floating and, according to theform, volume and location, assure the keeping of the head outside thewater, added of the possibility of complementary oxygenation, with theair reservoir accessed through the bidirectional biting valve (11).

For the welding of the neoprene, or similar, blades superimposed (110)are applied, in a first modality, at least one layer of an elastomericadhesive (22) is applied to the welding's internal line (20) from thelumen (10), in a manner to configure a mechanical barrier which canblock the exit of air through the permeation by the tissues' fibers, asindicated in FIG. 7.

As a second modality, as presented in FIG. 8A, the lumen's (10) weldingline (20) is limited by flaps to make the chemical attack of thetissue's internal face effective by the application of an acid, such asthe hydrochloric acid, collapsing the neoprene's lining (110) andconfiguring an area with thickness reduction and pores elimination (23),as presented in FIG. 8B, conforming a mechanical barrier which impedesthe escape of air contained in the inflatable tube (10), as highlightedin FIG. 8C.

The collapsed area (23) from the welding line (20) receives theapplication of adhesive or similar (22) for the collage, as presented inFIG. 8D.

In a third modality, as presented in FIG. 9, at the lumen's welding line(20) is a trench configured (24) by removing the neoprene blade'sinternal lining (110), in a manner to eliminate any area with fiberswhich allow the entrance of air. At the trench (24) is applied, atleast, a layer of adhesive product or the like (22) which impedes airoverflow, being the welding line (20) next sympathized to the opposingblade (100) through an adhesive (22).
